Specification of Letters Patent.

' Patented Mar. 5, 1912.

Application filed August 5, 1910. Serial N 0. 575,744.

To all whom it may concern:

Be it known that I, THOMAS WRIGHT, a citizen of the United States, residing at Jersey City, in the county of Hudson and State of New Jersey, have invented a new.

and useful Coal-Wagon, of which the following is a specification.

This invention relates generally to wagons and particularly to the type used for carrying coal and other similar material.

One of the objects of the invention is to provide improved means for elevating the body of the wagon above the truck thereof when it is desired to discharge the contents down a chute or incline.

A further object 'of' the invention is to that changes in the precise embodiment ofv invention herein disclosed can be made within the scope of the claims without departing from the spirit'of the invention.

In the accompanying drawings forming part of this specification, Figure 1 is a side elevation of a coal wagon constructed in accordance with the present invention. Fig. 2 is a view similar to Fig. 1 showing the body of the wagon raised above the truck thereof, and illustrating particularly the shape of the wheeled lifting arms, a portion of the side of the body of the wagon being broken away so as to show one of the bottom sections in raised or inclined position. Fig. 3 is an end elevation loo-king at the rear of the wagon with the body thereof raised above the truck, a portion of the rear end of the wagon being broken away in order to show one of the bottom sections in raised position. Fig. 4 is a detail view in under plan of one of the sets of lifting arms. Fig. 5 is a diagrammatic view showing one of the curved lifting arms in an intermediate position. Fig. 6 is a side elevation of a wagon equipped with a slightly modified arrangement of lifting levers.

Like reference numerals indicate corresponding parts in the difierent figures of the drawings.

The coal wagon of the present invention .is provided with front wheels 1 having a lower bolster member 2 connected therewith and cooperating with an upper bolster member 3. Rear wheels 4 serve to support the rear bolster 5. Supported upon the bolsters 3 and 5, as shown in Fig. 3 of the drawings is a truck bottom 6 which'is provided with longitudinally extending side plates or-sills 7 on which the body 8 of the wagon rests when it is in lowermost positlon.

For the purpose of guiding the wagon body 8 in its vertical movement, said body is provided with depending vertical arms 9 which are bifurcated at their upper ends as shown in Fig. 1 and suitably bolted at 10 to the wagon body. The lower portions of sald guiding arms 9 extend slidably through brackets 11 bolted at 12 upon the sills or side plates 7 of the wagon truck.

The means for raising and lowering the wagon body 8 upon the truck of the wagon preferably includes a plurality of curved lifting arms 14. Each of the lifting arms is pivotally connected at 15 at its upper end to a pair of parallel links 16, shown best in Fig. 4 of the drawing. Each pair of parallel links 16 is pivotally mounted at 17 upon a bracket 18 bolted or otherwise suitably secured at 19 to the bottom of the wagon body. At its lower end, each of the curved lifting arms 14 has journaled thereon at20 a roller or anti-friction device 21 preferably in the form of a grooved wheel as shown in Fig. 3, the wheels 21 being connected wit-h each other in pairs, by means such as the axles 23. It will thus be seen that each arm is movable bodily relative to both the wagon body and the truck whereas structures heretofore devised and which employ lifting arms, have had the arms pivotally connected either to the body or to the truck. The grooved wheels 21 run upon tracks 24 which are suitably supported upon the bottom 6 of the truck of the wagon. The tracks 24 as clearly indicated in Fig. 2 of the drawing, are dipped or depressed at their forward and rearward ends.

The means for causing the pairs of rollers 21 to be moved toward each other on. the tracks 24 so as to elevate the wagon body 8 preferably includes a pinion mounted on a squared shaft 31 and meshing with a large gear wheel 32 fixed on a shaft 33. Also fixed on the, shaft 33 is a pinion 34 which meshes with a large gear wheel 35 fixed on a shaft 36. The shaft 36 at its center has fixed thereon one or more winding drums 37 as shown in Fig. 3 on which are wound chains 39 which extend around wheels 40, mounted on the shafts 23 of the wheels 21 and are fixed or otherwise suitably secured: at 41 to the truck body. By winding on the squared shaft 31, the chains 39 are wound 1 bottom of the wagon body 8, would render;

it almost impossible to place enough power or purchase on the arms 14 to lift the wagon body 8 without fracturing said arms. By? employing the curved lifting arms 14 in combination with the links 16, they arms 14 roll against the bottom of the wagon body 8 as shown in Fig. 5 in the manner of cams and thus in effect decrease the active length; of the arms, when the wagon body is first; being lifted, to a distance approximately equal to the distance from the center of the wheels 21 to that point on the bottom of the wagon body 8 with which the curved por-f tions of the arms 14 contact. The lifting arms 14 thus produce the effect'of gradually lengthening lifting members as the wheels 21 are drawn toward each other into the position illustrated in Fig. 2. Q

The wagon body 8 is divided into four compartments by means such as the parti-,

tions 45 in Fig. 2 and each of these compartments is provided with a bottom 46 which is hinged or pivotally mounted along one lon-f gitudinal side edge thereof as indicated at 47 and is provided at the opposite edge with an eye or attaching member 48 to which is secured a chain 49. The chain49 extends upward over a pulley 5O journaled upon a bracket 51 which is secured to the upper edge of the wagon body. The outer end of the chain49 is secured at 53 to ahandle lever 54 which is fulcrumed at 55 upon a bracket 56 secured to the outside of the wagon body.' The handle lever 54 is provided with a hand grip 57 by means of which it can be drawn downward into the position illustrated by one of the'levers in Fig. 2 so as to lift the bottom 46 intothe inclined position shown in Fig. 3 of the drawings. The coal is thus caused in an automatic manner to flow outward through the member 63 into the telescopic chute 60 which is normally folded within the bracket 61 as shown in Fig. 2 of the drawings. The member 63 and the chute 60 can be arranged opposite the'door to any one of the four compartments.

The coal wagon of the present invention is strong, simple, durable and-comparatively inexpensive in construction as well as thoroughly practical, eflicient and economical in use.

In the modified construction shown in Fig. 6, the curved lifting arms 14 connected at 15 with the links 16 are further equalized in their actions by means of links 80 which are pivotally secured at 81 to the wagon truck and at 82 to the arms 14. In all other respects the construction and operation are the same as previously described and illustrated.

What is claimed as new is:

1. A wagon including a truck element, oppositely disposed similar cam-shaped arms supported thereby, a body element supported at all times solely by the arms, pivoted connections between the arms and the body element, and means for shifting the. arms along the truck element to roll the oppositely disposed arms simultaneously upon the body element.

2. A wagon including a truck element, a body element, oppositely disposed similar. cams interposed bet-ween said elements and constituting the sole supports for the body element at all times during the elevation of said element, means for shifting the cams bodily along one of said elements to roll them simultaneously upon the other element, and connections between the cams and the last mentioned element.

3. Awagon including a truck, oppositely disposed similar arms mounted. thereon and having curved bearing faces, a body mounted on and supported solely by said faces at all times during the elevation of the body, connections between the arms and body, and means for bodily shifting the arms simultaneously along the truck and relative to each other to. roll the arms upon the body.

4. A wagon including a truck, oppositely disposed cam shaped arms supported thereby, a body bearing on and supported by the arms at all times during the elevation of the body, connections between the arms and body, and means for simultaneously shifting the arms toward or away from each other on the truck to roll the arms upon the body.

5. A wagon including a truck, a body, cam-shaped arms supported by the truck and having convexed bearing faces engaging the'body at all times during the elevation of the body and constituting the sole support lower ends of the arms upon the truck and relative to each other to roll the arms upon the body.
